The song, which was recorded post-‘In Utero’ in January 1994 at Bob Lang’s Studio in Seattle, has been at the centre of a legal wrangle between Courtney Love and surviving band members Krist Novoselic and Dave Grohl.

Earlier this year, fans claimed to have found four short clips of the track, which is set to feature on a future Nirvana compilation album. Now, fans claim to have found the entire track.

According to the unofficial Nirvana website, www.nirvanaclub.com, ‘You Know You’re Right’ appeared online on the evening of September 21. The track is said to be a “complete high quality recording”.

However, Courtney Love said that an official Nirvana release, which could feature the track, will come out before the end of the year.

Speaking on the ‘The Howard Stern Show’ in the US, she said: “You’ll get the new Nirvana record at Christmas. We love each other. We’re getting along. We worked it all out.”

It is currently unclear what the new Nirvana release will be. There is talk of a single compilation album containing the band’s biggest hits and ‘You Know You’re Right’, but the original plan was to release a box set of rare and unreleased material.
